First Class Metals Secures 80% Interest in Zigzag Critical Minerals Project After Completing Earn-In

First Class Metals has done the bit that really matters here – it has finished the Zigzag earn-in and officially secured an 80% interest in the project. In plain English, FCM has met the agreed cash, share and exploration spending commitments, and that now hands it operational control of Zigzag.

For retail investors, this is more than paperwork. It moves Zigzag from being an optioned exploration play into an asset FCM actually controls, with the project now shifting into an 80:20 joint venture with Nuinsco Resources.

First Class Metals Zigzag earn-in completed – the key numbers investors should know

Item	Detail
FCM interest in Zigzag	80%
Nuinsco interest in Zigzag	20%
Ownership structure now	Joint venture
Distance from Green Technology Metals’ Seymour Project	Approximately 10 km
Highlighted drill intercept	4.3 m @ 1.65% Li₂O
Highlighted drill intercept	5.0 m @ 1.50% Li₂O
Highlighted drill intercept	6.5 m @ 1.09% Li₂O

Why First Class Metals taking control of Zigzag matters

An earn-in is a staged way to buy into a project by meeting agreed commitments over time. FCM has now completed those obligations, so this is the point where the company turns effort into ownership.

That is important because exploration stories often get stuck in the “interesting but not yet secured” category. Zigzag is now firmly in FCM’s hands as operator, which means the company can drive the next work programme rather than just talk about potential.

There is also a credibility angle here. Completing an earn-in shows management followed through on a multi-year agreement first signed in March 2023, and that matters in junior mining where missed milestones can quickly damage confidence.

Zigzag lithium project results – what the drilling says so far

The project already has drill-confirmed lithium mineralisation, which is the central technical point in this announcement. The standout intercepts disclosed are 4.3 m @ 1.65% Li₂O, 5.0 m @ 1.50% Li₂O and 6.5 m @ 1.09% Li₂O.

Li₂O means lithium oxide, the standard way hard-rock lithium grades are reported. Those grades are meaningful for an early-stage exploration project, but investors should keep one thing straight – the company has not reported a mineral resource estimate here, so this is still not a defined ore body.

FCM also says the mineralisation remains open along strike and at depth. That is exploration language meaning the known mineralised zone has not yet been fully closed off by drilling, so there could be more to find in both directions and deeper down.

Critical minerals at Zigzag add extra upside beyond lithium

This is not being pitched as a one-metal story. Drilling has also confirmed tantalum, rubidium, caesium and gallium, all of which the company describes as significant multiple critical minerals.

That matters because by-product metals can improve project economics if they are recoverable in useful quantities. The catch is the key phrase here is “potential” – FCM has not disclosed grades, recovery rates, economics or likely revenue contribution for these metals, so investors should treat this as upside rather than bankable value today.

Still, strategically it is a decent angle. In a market where pure lithium stories can rise and fall with sentiment, having exposure to a broader critical minerals basket gives Zigzag a bit more resilience in the narrative.

Zigzag’s Ontario location near Seymour Project could be a real advantage

Location is one of the stronger parts of this RNS. Zigzag sits in the Seymour-Falcon pegmatite corridor in northwestern Ontario and is approximately 10 km from Green Technology Metals’ Seymour Project and proposed lithium processing infrastructure.

That does not guarantee shared infrastructure or future processing access, and FCM does not say there is any formal arrangement in place. But being close to an emerging regional hub is still valuable, because remote hard-rock projects can live or die on logistics, processing options and available expertise.

The board clearly thinks this nearby development boosts Zigzag’s strategic value. I think that is a fair point, though investors should remember it remains a strategic advantage, not a signed commercial deal.

What First Class Metals plans next at Zigzag – bulk sampling and metallurgical test work

Now that the earn-in is complete, FCM says it is evaluating a bulk sampling programme and metallurgical test work. Bulk sampling means taking a larger representative sample of rock, while metallurgical test work checks how well the lithium and other metals can actually be recovered during processing.

This is exactly the right next step for a project at this stage. Good drill grades are useful, but recovery is what turns a mineralised rock into a potentially economic product.

If recoveries come back well, Zigzag gets more interesting quite quickly. If they disappoint, then even decent-looking drill intersections may not translate into a viable development path.

My take on the First Class Metals RNS – the positives and the watchouts

What looks positive

• FCM has secured 80% ownership and operational control, which is a meaningful de-risking event.
• The project already has drill-confirmed lithium mineralisation with respectable reported intersections.
• There is added critical minerals exposure through tantalum, rubidium, caesium and gallium.
• The location near Seymour and proposed processing infrastructure strengthens the strategic case.
• The company says lithium market fundamentals are improving, which helps sentiment around hard-rock lithium projects.

What investors should be careful about

• This is still an exploration-stage asset with no mineral resource estimate disclosed in this announcement.
• No economics are provided – no capex, operating costs, NPV, IRR or development timeline are disclosed.
• Metallurgical recovery data is not disclosed, and that is a big missing piece.
• FCM owns 80%, not 100%, so future decisions sit within a joint venture structure.
• Funding requirements for the next phase are not disclosed in this RNS.

So my view is broadly positive, but measured. This is a solid project-control milestone rather than a transformational economic breakthrough.

Bottom line on First Class Metals and the Zigzag critical minerals project

This announcement matters because FCM has converted Zigzag from an optioned opportunity into an operated asset with an 80% stake. That gives the company real control over what comes next, and the next step – metallurgical work on a large representative sample – is the one that could start separating promise from substance.

For shareholders, the story is simple enough. The geology looks encouraging, the project sits in a good neighbourhood, and there is potential upside from both lithium and associated critical minerals. But it is still early, and until recovery data and a clearer development path arrive, Zigzag remains an interesting exploration asset rather than a proven commercial project.

That is not a bad place to be. It just means the market will probably want technical evidence from the next phase, not just a stronger ownership position.
